Soma Rush.... 53cm or 55cm
I am looking to pick up a Soma Rush and can't figure out which size to go with. I am 5'9" with a ~31.5" inseam. My current road bike (with compact geometry) has me with a 54cm effective top tube length paired with a 110mm stem. Looking at Soma Fab's site (https://www.somafab.com/geometry03.html) it looks like I might be able to go with either one. Just wondering what their "real world" fit is like....

I'm the same height as you and I have a 55cm. I bought mine on ebay and the seller called me to confirm the size and told me that the geometry of the Rush is similar to the Bianchi Pista Concept. I've ridden a 57cm Concept before and told him that it fit me well, so he told me to go for a 57cm Rush. I went against his advice and to be honest I should have listened to him. The frame geometry is good as it is but I believe the 57cm would have been perfect.
Hope this helps.

OP, personally based on what you told us, I'd go for the 53cm - you can stretch out the top with a longer stem if you need to & the smaller frame will be a bit more agile (shorter wheelbase, etc.).
I'm 5'11" with 32" inseam & ride a 55cm frame track bike with almost identical geometry, even though my road bike is a 58cm.
That's my $0.02

I'm 5'8" with a 32" inseam, and ride a 54 or 55. I'd recommend the 55. My 54 touring bike is a small as I would be able to go, and it would be even better if that frame came in a 55. My road bike is a 55.

The 53cm's top tube is much closer to your current bike's top tube (just 4mm short).
Also, the seat tube angle is steeper than on a typical road bike, which means if you set up your seat in the same position relative to the bottom bracket, the Soma's top tube will effectively lengthen.
53cm sounds like it will be much closer to your current bike.

id go with the 55. i am 5'10" and ride a 53 soma rush. i wish i had gone with the 55. there is a good deal of saddle to bar drop even with more spacers than id like to use. my road bike is a 56 and fits me more appropriately. i believe my inseam is around 32"

I am 5'9" (with 31" inseam) and I have 53cm Rush Seat angle is so steep that it feels very long. It feels longer than my roadbike with 548mm TT. If I were you, I'd took 53cm.

hey all.... thanks for the input. it really sounds like i could probably make it work either way.
anyhoo, i ended up getting a good deal on a lightly used Bareknuckle (52cm)... so i ended up impulsively pulling the trigger on that. fortunately i *was* able to throw a leg over that bike and confirmed that it seemed fit right for me!
can't hardly wait to start riding it regularly.... should be fun!
